T o all whom it may concern:

Be it known that I, PHILIP W. Moena, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Anticreepers, of which thefollowing is a full, clear, concise, and exact description, referencebeing had to the accompanylng drawings, forming a part ofthisspecification.

Mv invention relates to improvements in anti-Creepers for railroad railsof the general type wherein the creeping thrust produces a tendency totilt the anti-Creeper about a horizontal axis at right angles tothelength of the rail, said tilting action tending in increase the holdof the anti-creeper on the rail base.

The objects of my invention are: To provide a rail anchor `whichmaintains an e'ective hold on the rail base when the forward thrustagainst the tie is relieved. To provide a rail anchor in which a veryfirm grip on the rail base may be secured independently of the tiltingaction. To provide a rail anchor of this type, of generally improvedconstruction and increased elliciency in holding the rail.

I have illustrated in the accompanying drawings a rail anchor whichembodies the invention and which has various practical advantageshereinafter pointed ont. The invention may, of course, be embodied indifferent forms.

Figure 1 of the drawings is an elevation of the rail anchor aembled onthe rail. Fig. 2 is a top plan view thereof. Fig. 3 is a Side elevationthereof. Fig. 4 is a perspective view of the main part or yoke. Fig. 5is a perspective view of the smaller part or mate.

The usual cross-tie l supports the rail 2 in the customary manner. Therail anchor is applied to the rail adjacent to the crotie and, in theform illustrated consists of two parts which may be termed forconvenience the yoke 3 and the mate 4. The volse is provided with hooksor jaws 5, 6 at the opposite ends thereof. The jaw 5 is adapted to fitover and bear down on the upper surface of the rail base. The jaw 6.Cldl'S the opposite side of slid base and r* @elves loosely the mate 4,which latter grips the edge of the rail base. (See particularly Figs. land E of the drawings.) The transbeing indicated by the arrow. A pairof.

downwardly extending flanges 8, 9 is provided to bear against thevertical face of the cross-tie. The general relation of the parts issuch that when the rail tends to creep, the yoke tends to tilt, wherebythe cross bar 7 bears upwardly against the bottom of the rail and theportions of the jaws which overlie the rail base bear downwardly towardthe top thereof to increase the rictional grip thereon of the parts ofthe anchor in direct contact therewith. (See Fig. 3).

n auxiliary jaw 10 is provided at one end of the cross bar 7, adapted togrip the edge of the rail base at a point nearly in line with said crossbar. The rail is, therefore, en aged by two jaws on this side, one ofwhic engages only the top surface of the base and the other whichengages it both above and below. The mate 4 is arranged about oppositethe space between said tlvlvoijaws and is prlvided with a diubl; jaw ormg e op osite si e o said rail basnp'lzhe jaw 11 is, in effect, a

single jaw having a central part cut away as shown at 12, therebyproviding .`a locking recess hereinafter referred tol Said mate has alsoa downwardly extending rib 13 which is somewhat under-cut to match acorrespondingly under-cut wall 14 on the end of the cross bar 7 oppositethe jaw 10. The engaging surfaces just mentioned are not only inclinedfrom a vertical plane to provide for an interlocking thereof, but theyare also arranged somewhat diagonally with respect to the length of therail, whereby as the mate is caused to slide along the wall 14 it iscrowded inwardly toward the rail so as to cause the jaws 5, 10 and 1l togrip the rail base firmly between them. A flexible extension or tongue15 projects rearwardly from the jaw 6 and may be bent down into therecess 12 of the mate to lock the same against a rearward movement afterthe rail base has been firmly gripped by the jaws in the manner justdescribed.

In applying the device to the rail, the yoke is first put in place byhand, said yoke being suiiiciently cut away beneath the jaws 5 and G topermit it to be readily positioned. The mate 13 is then fitted in placeand driven toward the tie with a heavy hammer or maul as far as it canbe driven, the anges S, 9 being so positioned with r.espect to the tie,that they bear firmly against the latter when the parts are in Qposition, as shown inFig. 3. Not only is the rail gripped between thejaws 10 and 11, but the Jaw 5 also lits over the side and top of therail base and as the mate is being driven toward the tie, the tendencyis for the rail anchor to tilt about a horizontal axis transverse to thelength ofthe rail and located possibly about where the cross bar 7 comesin contact with the base of the rail. The jaw 5, therefore, bears downfirmly against the top of the rail base, and the jaw 6 bears down firmlyagainst the top of the mate l thereby developing considerable friction.As previously stated, the mate is locked against a rearward movement,after having been driven toward the tie as far as possible. When therail tends to creep in the direction shown by the arrow in Fi 2, thetendency is for the rail anchor to t in the same manner as instdescribed, whereby a powerful gripping'` action is between the cross bar7 which exerts an upward thrust on the rail base and the jaws', 6 and 11which exert a downward I thereon. 'Ihe downwardly extendinganges S and 9transmit the creeping thrust' to the tie. The intention is to have bothilanges bear against the tie, but where the latter happens to be soirregular that only o ne flange bears against the action resultsnevertheless, the device ef,- fective in either case to prevent It isobvious that the frictibnal hold is maintained on the base as lon y asthe thrust against the tie continues. Sai rail anchor maintains itshold,` however, even when said thrust is Sadi relaxaion'occurs when arearward movenient of the rail takes place due lto a reversal of traicor to a caused by cold and for other danses. Said hold maintained underthese conditions because of the fact that the mate has been driven toand locked in such a' position as to draw the jaws on the opposite sidestoward each other and furthermore the jaw 1B is located somewhat to therear of the ftion of the cross bar 7, so that any tendency of the railanchor to tilt in the opposite direction from which it normally tends totilt, is prevented by said jaw as well as by the general tight fit ofall of the parts. Such rearward moves ment sometimes developsconsiderable stress tending to tilt the anchor, where the ballast isfrozen and the H anges 8, 9 embedded therein. For this reason, theprovision of the auxiliary jaw 10 is important as it off ers a positiveobstruction to tilting in such a direction as would tend to relax thegrip between the rail anchor and the rail base.

Various changes may be made in the details of construct-ion withoutdeparting from the spirit of the invention, as expressed in the appendedclaims.

Havlng thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:
